▎ 摘　　要

NOVELTY - Method to fabricate nanostructures, comprises spin coating a charged electrostatic layer onto a substrate, depositing a charged colloidal solution having an opposite charge from the electrostatic layer, applying a mask layer over the electrostatic layer and colloidal solution, removing the colloidal solution along with any mask material on the colloidal solution, etching the substrate and electrostatic layer in the locations that the charged colloidal solution was removed from, via the remaining mask, depositing a biocompatible layer, and de-molding the biocompatible layer. USE - The method is useful for fabricating nanostructures useful in lens and to read biomaterial from solution (all claimed) for glare reduction, antibacterial surface and Raman spectroscopy for analyzing biomaterial. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) lens (100), comprising a nanostructures layer (101); and at least one sensor layer (102), where the nanostructures layer further comprises a surface having nanostructures arranged in a quasi-random distribution; and (2) method to read biomaterial from a solution, comprising depositing a biomaterial solution onto a nanostructures layer, drying the biomaterial solution on the nanostructures layer to form a coffee-ring pattern of concentrated biomaterial, performing drop coating deposition Raman spectroscopy (DCDRS) on the coffee-ring pattern of concentrated biomaterial, and identifying the biomaterial from the DCDRS. DESCRIPTION OF DRAWING(S) - The figure shows a top view of an example embodiment of a smart contact lens with a nanostructures coating, multiple sensing elements and nanowire.
